iteration on record?

[fmarletaz]

Thanks for developing pyfastx, that's a really nice tool! However, I have a basic question. When you iterate over the fasta object or the pyfastx.Fasta(command, does it always report name and sequences as string. What if I want to iterate over sequence objects to rename them using the description field. Maybe I missed something. Thanks again!!!

Yes, current version for fasta object iteration can only return a tuple with string of name and seq. But you can use keys for iteration to make a sequence object for additional information. For example:

fa = pyfastx.Fasta('your_fasta.fa')
for name in fa.keys():
    s = fa[name]
    print(s.description)

In future version, iteration for sequence object from fasta object will be added.
